ROAD-GRADING MACHINE AND JDI'ICHER.

Specification of Letters Eatent.

Patented Feb. 8, 1916.

Application filed January 25, 1915. Serial No. 4,207.

To all whom it may concern Be it known that I, WILLIAM R. WIL- LIAMS, a citizen of the United States, residing at Owensboro, in the county of Daviess and State of Kentucky, have invented a new and useful Road-Grading Machine and Ditcher; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a new and useful road grading machine and ditcher.

As an object of the invention it is the aim to improve and simplify, as well as render more practical, the structure of road grading machines, set forth, shown in the drawings and claimed in the a plication filed April 1, 1914, Serial No. 828, 16 in the name of W. R. Williams, which application has matured into a patent issued Mar. 2, 1915, Patent No. 1,129,936.

Another object of the invention is the provision of a machine of this nature having a cutting blade which is designed to be used for ditching and deep cutting.

In practical fields the details of construction may necessitate alterations, falling within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings :Figure 1 is a plan view of the improved road grading machine, showing the same provided with the cutting blade, which in turn is supplied with an extension leveler blade. Fig. 2 is a view in side elevation of the machine as shown in Fig. 1. Fig. 3 is an enlarged detail perspective view of the cutting blade showing the extension leveler applied.

Referring more particularly to the drawings, 1 designates an elongated runner, to the forward end of which a plate 2 (which is bent upon itself to form a bearing 3) is secured, as shown at 4. The opposite portions of the plate 2 are secured upon oplplpe runner has secured to one face thereof a T-angle iron 5, which constitutes a reinforcing means- This T-angle iron is secured at 6, and is provided with a plurality of apertures 7, the purpose of which will appear later. Carried by the runner 1 is a pair of brackets 8, which support the balancing or platform board 9. It is to be noted that an operator may gage the cutting depth of the runner, by varying the weight upon the platform. For instance, the operator by standlng upon the platform toward its forward portion would cause the runner to produce a deep cut, and by standin adjacent the rear, the cut may be lessene considerably, and by standing in the center of the platform, and by alternately varying the weight first toward the front and then toward the rear, a medium but regular cut may be made. The forward portion of the runner 1 is also provided with a pair of hooks 10, designed to enter the apertures 11 of the cuttlng blade 12, for connecting said blade to the runner, in the manner as shown in the drawings. The cutting blade 12 is concaved, as shown, and which concavity is equal from the top and bottom edges toward the center, as shown, and also extends almost the full length of the blade, however, dllllIllSlllIlg or vanishing toward the rear en The rear face of the cutting blade is provided with an angle iron 15, constituting a reinforcing means for the cutting blade.

Also secured to the rear face of the cutting blade 12 adjacent the rear end thereof is a metallic strap 16, bent to form two arched portions 17 and 18, either one of which being designed to receive the extension leveler or blade 19, the extremity of which is provided with a cutting tool or member 20.v

The extension leveler or blade 19 is supplied with a plurality of apertures 21, to receive the hook 22, in order to hold the leveler in adjusted position. Also carried by the rear end portion of the cutting blade is a lift handle or member 22*, used for turning or assisting in inverting the machine, on which handle or member 22, the hook 22 is pivoted. Adjacent the rear end portion of the cutting blade, and upon its rear face is a pair of straps 23. forming bearings to receive the angled end 24 of the link 25 (which is substantially U-shaped as shown) and to this link 25 an elongated link 26 is pivotally connected. The other end 27 of the link 26 is slotted, as shown at 28, and is formed in eyes 29. The slotted end 28 receives the '1!- portion 30 of the IF-iron 5, and a pin 31 passes through the eyes 29, and through any one of the apertures 7, in order to adjustably connect the elongated link 26 to the T- iron. By this method of connection the cutting blade may be held at difi'erent angular shown. A pin extends through the bearings 3 of the plate 2, to pivotally connect the hitching member or bar 36 in place, which is received in the slot 37 of said plate 2. A clevis member 38 (to-which an evener,

or equalizer (not shown) may be connected) 'is connected at 39 to the hitching member or bar 36, so that a machine may be drawn over the roads.) The hitching member or bar 36 is provided with several apertures 40, in any one of vwhich one end of the link 34 may be connected, so as to connect the hitching member or bar 36 to the cutting blade. It will be observedthat as a pulling force is exerted upon the hitching member or bar 36 and the link 34, the cutting blade 12 is held in proper position, holding the links 26 and 25 alined. However, if the pulling force is not so great, or that the cutting blade strikes an obstruction in its ath, the links 25 and 26 will collapse slight y, but just so soon as the obstruction is removed or passed, the links will again become alined. The rear end of the runner is provided with a pair of anchor blades 42 and 43, secured in place, as shown at 4:4. These blades are designed for the purpose of guiding the runner, and holding the same alined, and are so positioned on the runner that the runner, in fact the entire machine, may be inverted. These n a road grading machine, a land side Y bo y member, a scraper blade connected at its forward end to the forward portion of the body member and extending laterally and rearwardly at an angle to the body member, connections between the-rear lateral. end of the blade and the body member, the rear lateral end of the blade having upon its rear face a strap, bent to form two rectangular arches, a handle member fixed between the arches, an extension leveler blade-to be received adjustably in either one of the "arches, said leveler blade having vertical apertures, and a T-shaped hook pivoted to the handle member and having its T-shaped portion to' engage any one of the apertures to hold the leveler blade in adjusted position in either one of the arches.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. 3
